Abstract

Provided is a light emitting device having an upper/lower electrode type light emitting diode on a substrate composed of a ceramic board composed of a metal substrate and a ceramic substrate abuttingto the metal substrate. A substrate lead frame for manufacturing the light emitting device is also provided. In the light emitting device, a light emitting section or the like is arranged on a substrate wherein a metal substrate (11) and a ceramic board (12) abut to each other on one side. The ceramic board (12) has a conductive film (17) formed on an upper section. The metal substrate (11) and the ceramic board (12) are bonded with an adhesive such as a thermosetting resin so that a reflection frame (16) composed of an insulating member having an opening section is over the metal substrate and the ceramic board. At least one upper/lower electrode type light emitting diode (13) has a lower electrode on the metal substrate (11). At least one conductive connecting member (14) connects an upper electrode (131) of the upper electrode type light emitting diode (13) and the conductive film (17).
